High Yield Investment Programm

Definition

A High Yield Investment Programm or HYIP is a website that give you a lot of interest (usually 1-10% of your investment a day).
So where does the money comes from ???
The answer is quite simple: From the other members (or sometimes from trading, forex) !
So be careful, it's always the same with the HYIP: The websites open, they pay the members, they get a lot of money, and after some weeks/months they stop paying and become scams !
In conclusion, you can make a lot of money by adding some dollars and try to get them back after a few weeks/month, before they stop paying.

Calculate the earning

Here is the mathematical formula:
Investment + Earning = u1 * qn-1

Where:
u1 is the starting amount.
q is the multiplier per unit of time: (100 + the pourcentage) / 100.
n is the number of units of time
